Application fded December 6, 1919. Serial No. 342,899.. l

To all whom t may concern:

4Be it known` that I, ROBERT LELAND K1N- GAID, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful lVashing-Machine, of which the following is a specification.

This invention has for its object a washing machine which is particularly simple in construction, composed of a minimum number of compactly arranged' parts and which is highly ellicient and dura-ble in use; the invention consists in thecombinations and constructions set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in whichlike characters designatel corresponding parts in all the views.

Figure 1 is a sectional view of a washingl machine embodying my invention. FFig. 2 is a sec-tionalview on line 2 2,

Fig. 3 is a plan view of thediaphragm. Fig. 4 is a section on line 4 4, Fig. 3'. Fig. 5 is a det-ail view of the rim of the diaphragm.

Fig. 6 is a sectional view on the plane of line 6 6, Fig. 2.

This washing machine comprises generally, a receptacle or tub, a. vlbratory dla- -phrlagm detachably mounted in the tub and having a rim, the receptacle and the rim coacting to hold the diaphragm from bodily displacement and also holding'the rim from vibratory movement, and means connected to the central portion of the diaphragm to vibrate the same while its rim is held stationary.

' 1 designates the receptacle or tub which may be of any suitable form, size and construction.

2 designates the diaphragm which is here shown as a disk of flexible material as canvas formed with eyes or metal lined perforations 3 through which water washes during the vibrations of the diaphragm.

This diaphragm is provided with suitable metal rims 4 to which the margin of the disk is connected, the rim being expansible and contractile. As here shown it is in the form of a split metal ring and having its ends connected by a link 5 pivoted at each end to one end of the ring. As here shown, this rim is also formed with an inwardly extending loop 7 diametrically opposite Aits ends,

this loop facilitating the expansible and contractile feature and also forming a passa-ge for the part of the actuating mechanism as will be hereinafter described. The rim is also formed with a pair`of handles 8 by means of which the diaphragm can be lifted out of and placed into the receptacle.

In the illustrated embodiment of my inventlon, the receptacle is formed with an internal annular groove 9 for receiving the rim 4, and after the diaphragm has been placed in the receptacle and pushed down' unt-il the rim enters or snaps into the groove,

the rim is expanded into the groove, the link/ 5 connng into the are of the ring and locking the ring expanded. The diaphragm is vibrated by suitable mechanism preferably connected -to the `lower side of the diaphragm. Q v

The diaphragm -is also formed with valve controlled return passages 10 for the water. These passages are formed near the margin of thediaphragm and the valves or flaps 11 on the upper side of the disk covering the passages 10. lVhen the diaphragm moves downwardly the water is pushed up through the passages 10 raising the flaps 11 and also through the perforations in the diaphragm,

but when the disk is moving upwardly the flaps close the passages and compel the water to pass through the clothes on the diaphragm. The receptacle is also formed with .return pipes 12 connecting the space below the diaphragm with that above the diaphragm. Thus, during downward movement of the diaphragm the water is forced up through the pipes 12.

The perforations of the diaphragm are `more or less obstructed by the clothes on the diaphragm and hence the marginal passages 10 or the return pipes 12 are provided to avoid stopping or retarding of the ma- As here shown, the intermediate part vof the' diaphragm is formed with a metallic center piece having a depending bearingv 18 to which the pivot 19 of the upper\end of the link 17 is connected.

The actuating means for the lever 13 comprises a suitable motor 20 here shown as .mounted on the frame 21 of the machine which frame supports the tub or rece tacle, the upwardly extending shaft 22 having a gear as a worm gear 23 at its lower end meshing with the worm 24 on the motor shaft 25 `and having a bevel gear 26 at its upper end meshing with the bevel gear 27 mounted on a shaft 28 journaled in the bearing 29 supported by the upright wall of y a receptacle,- a frame extending upwardly along said wall, the shaft 28 extending to the inside ofthe receptacle and having a,

crank arm 30 thereon.

A link 31 connects the crank pin of the arm 30 and the short arm 16 of the lever 13. This link extends through the loop 7 of the rim l of the diaphragm as does also `a casing inclosing this link andthe crank arm 30. Obviously during actuation of the motor, y the link '31 will be reciprocated moving the lever arm 13 upwardly and downwardly and oscillating the diaphragm. The clothes are placed on the diaphragm andl the water placed in the tub to a suitable level and 30 during the oscillation of the diaphragm the water is passed 'to and fro through the clothes on the diaphragm through the diaphragm and perforations therein. The diaphragm is readily placed in position either 35 alone or with the clothes thereon by means ooi" the handles 8.

' The shafts 25, 22 andy 28 may be vmounted in any suitable arrangement of bearings supported by the frame, andthe shaft 22 and 40 gears thereon, and coactingk therewith are inclosed with the suitable casing 32.

The casting 15 is also usually secured to a leg or framev member extending vertically along the outside of the tub. The tub is also provided witha valve controlled outlet.

What I claim is:

1. A washing machine comprising a receptacle, a vibratory iexible and perforate diaphragm mounted in the receptacle for supporting the clothes, means for holding thevrim of the diaphragm against movement relatively to the receptacle, the middle portion of the diaphragm being movable above and below the horizontal plane of its rim,

and actuating vmeans connected to the middle of the diaphragm, substantially as and for the purpose described.

2. A washing machine comprising a receptacle, a vibratory flexible and perforate diaphragm mounted in the receptacle for supporting the clothes, the diaphragm being in the form of a sheet formedV with water passages, means for holding the rim of the diaphragm against movement relatively to the receptacle, substantially as and for the purpose specified.

3. A washing machine comprising a receptacle, a vibratory flexible and perforate diaphragm mounted in the receptacle for supporting the clothes, means for holding the rim of the diaphragm against movement relatively to the receptacle, the diaphragm being in the form of a discoidal `sheet and its central portion being movable below and above the plane of its rim, and actuating means connected to the middle of the diaphragm, the actuating means including a member located below the diaphragm and connected to the same centrally thereof, substantially as and for the purpose set forth.

4. A washing machine comprising a receptacle, a flexible and perforate diaphragm mountablein the receptacle and having an expansible and contractile rim Jformed with an inwardlyextending loop, the receptacle having means for coacting with the rim to hold the same from vibratory movement,"

means for actuating the diaphragm including members extending through said loop to the lower side ofthe diaphragm and the member` actuated by said means and connected to the central part of the diaphragm, substantially as andV for the purpose described.

5. A washing machine comprising a receptacle, a vibratory flexible diaphragm mounted in the freceptacle for supporting the clothes, means for holding the rim of the diaphragm against movement relatively to the middle of the diaphragm, the diaphragm being formed with valve controlled passages therethrough, and means connected to the central portion of the diapiirfgm y for reciprocating the same relatively to its rim, substantially as and for the purpose specified.

6. In a washing machine, a tub or receptacle, a discoidal perforate diaphragm in the receptacle, means for holding the rim of the diaphragm from movement and means connected to the central part 0I" the diaphragm for reciprocating it from below the level of the rim to above said level and vice versa.

In testimony whereof, I have hereunto slgned my name, at Syracuse, in the county of Onondaga, and State of New York, this" 17th day of November, 1919.
